Cedric has a low fever and minor aches. yesterday, he went to the doctor for his booster shot and received the flu shot. which best explains why he has this reaction? a. cedric was given an antibiotic. b. cedric was too old for the vaccine. c. the weakened virus stimulated the immune response and resulted in the minor reaction. d. the vaccine contained antibodies that caused cedric to make more antibodies.

The right answer is C.

There is a much higher risk of severe complications from influenza than of vaccine-related adverse events.

Of these adverse effects, the most common (for 10-40% of people vaccinated) is redness or pain at the injection site. Other symptoms can also be observed in 5 to 10% of the vaccinated: fever, muscular pain or slight nausea.

These reactions are benign and disappear at the latest after a few days.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

sorry, but you do not have posted the diagram.
